USPP19014P2 - Papaver plant named ‘Casino’ - Google Patents

Abstract

A new, and distinct cultivar of Papaver plant named ‘Casino’characterized by its upright plant habit; moderately vigorous growth habit; and large flowers with white and black-colored petals.

Description

Botanical designation: Papaver orientale.

Cultivar denomination: ‘Casino’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Papaver, botanically known as Papaver orientale and hereinafter referred to by the name ‘Casino’.

The new Papaver originated from a cross-pollination of two unnamed selections of Papaver orientale, not patented. The new Papaver was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled environment in Oudelande, The Netherlands in May, 2003.

Asexual reproduction of the new cultivar by divisions since 2004 in Oudelande, The Netherlands has shown that the unique features of this new Papaver are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Casino have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Casino’. These characteristics in combination distinguish ‘Casino’ as a new and distinct cultivar of Papaver:

• • 1. Upright plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Large flowers with white and black-colored petals.

Plants of the cultivar Casino differ from plants of the parent selections primarily in flower color and plant height.

Plants of the new Papaver can be compared to plants of the Papaver orientalis cultivar Perry's White, not patented. In side-by-side comparisons conducted in Oudelande, The Netherlands, plants of the new Papaver differed from plants of the cultivar Perry's White in the following characteristics:

• • 1. Plants of the new Papaver were shorter than plants of the cultivar Perry's White.
  • 2. Plants of the new Papaver had larger flowers with more petals than plants of the cultivar Perry's White.
  • 3. Flowers of plants of the new Papaver were white and black in color whereas flowers of plants of the cultivar Perry's White were creamy white and black in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Papaver.

The photograph on the first sheet is a side perspective view of typical plants of ‘Casino’ grown in an outdoor nursery.

The photograph on the second sheet is a close-up view of a typical flower of ‘Casino’.
